Vestibular and Proprioceptive System

Trenton always has sensory problems. However, the last week it has been bad. Andrew has sensory problems too and his problems are becoming more evident as he gets older.
Trenton has had some major issues with his vestibular and proprioceptive systems the last week.
Here is some information on these....
Vestibular System: The vestibular system refers to structures within the inner ear (the semi-circular canals) that detect movement and changes in the position of the head. For example, the vestibular system tells you when your head is upright or tilted (even with your eyes closed). Dysfunction within this system may manifest itself in two different ways. Some children may be hypersensitive to vestibular stimulation and have fearful reactions to ordinary movement activities (e.g., swings, slides, ramps, inclines). They may also have trouble learning to climb or descend stairs or hills; and they may be apprehensive walking or crawling on uneven or unstable surfaces. As a result, they seem fearful in space. In general, these children appear clumsy. On the other extreme, the child may actively seek very intense sensory experiences such as excessive body whirling, jumping, and/or spinning. This type of child demonstrates signs of a hypo-reactive vestibular system; that is, they are trying continuously to stimulate their vestibular systems.

Proprioceptive System: The proprioceptive system refers to components of muscles, joints, and tendons that provide a person with a subconscious awareness of body position. When proprioception is functioning efficiently, an individual's body position is automatically adjusted in different situations; for example, the proprioceptive system is responsible for providing the body with the necessary signals to allow us to sit properly in a chair and to step off a curb smoothly. It also allows us to manipulate objects using fine motor movements, such as writing with a pencil, using a spoon to drink soup, and buttoning one's shirt. Some common signs of proprioceptive dysfunction are clumsiness,
a tendency to fall, a lack of awareness of body position in space, odd body posturing, minimal crawling when young, difficulty manipulating small objects (buttons, snaps), eating in a sloppy manner, and resistance to new motor movement activities.

Trenton seems to be hyposenstive and need a lot of pressure on his I am talking weights! Unfortunately when he is having trouble feeling his body in space, he needs a lot of  input on his body. He tried to control it by running and jumping on furniture, hitting everything, swinging his body around, swinging his arms, shaking his head back and forth non stop, and having a lot of anxiety.

What I need to do is bounce him on his therapy ball, put pressure on his legs and body, put his compression garments on, make him lay down with his weighted blanket, swing him in his swing, and many many other things.Its constant non stop sensory input on these days and its been going on for a full week! UGH!
It has definitely interred in his therapies this week so far.
All I can say...its one crazy household..... I can't imagine not feeling my body.

Andrew, on the hand, is hypersensitive. His body is very sensitive. Andrew will cry at the drop of a hat. He can barely rub his elbow against a chair and he cries. However, to him it feels like a knife stabbing him. Hence, the reason why he feels very fearful at times.
Tonight was the first time in one week that Andrew let me bathe him. He has screamed at water touching his skin until today.

Both my boys have sensory issues and they are complete opposites as of right now. UGH!

With all of these issues, he also has major problems with his hearing. On some days he can't filter out all of the noise around him. He hears things that neurotypical people do not even hear. The other day when Daddy was mowing the yard, Trenton did not like the sound of the lawnmower from inside our house. To him, I am sure it sounded like 100 lawnmowers exploding only inches away from him. I was proud of him because he knew what he needed and he grabbed his headphones and wore them for awhile.
